Fitting a heavy awning

[johnny2007]

Hi guys and happy new year.
I bought an awning to go over the extension double doors but i didn't expect a such heavy product (30 kg).
Above the doors there are 5 lines of bricks and a flat roof constructed with 8x2 and strapped on the inside (9 years ago).
To allow headroom I should fit the two brackets at 20 cm above the door frame.
Each bracket have two anchors to be fitted on the third and fourth line of bricks.
My question is: Would the weight of the awning pull the bricks up?
In my mind I'm thinking that each anchor will hold 7.5 kg , but because they will be close to the last line of bricks I'm a bit concerned.
What do you think?

Doomed to failure.

It's not just the 30kg weight of the awning. When extended and a slight breeze occurs, the load on the fixings will be significantly more.

We saw a case of one of those awning-type carports that pulled the side of the house down when it had the extra weight of snow on it.

Remember the awning has tremendous leverage when it is extended.

I had a similar problem with an awning which was originally on the gable end of my bungalow. Following and extension build with a hip roof I was left with one course of blocks on a catnic lintel. I solved the problem with 2 off 8"x2" oak beams 8ft high bolted to the wall with 4 pairs of 12mm chemical fixings, vertically one each side of the patio door, bolts for the awning brackets were fitted through the oak from the back before fixing. The 8" width of the beam is wide enough to fit the brackets either side of suspension points of the awning. ( I will see if i still have a photo of the finished job)

Ok guys, thanks.
I will either desist and do without the awning or fit wooden posts that will further support the awning from the ground.
I'll have to see what the boss says (that's the wife )
You have probably saved me some very expensive structural repairs later.
